hello.
im looking for a PCB software that has tube PCB prints.
i tried some software like orcad and trax maker but i need it to route a single layer and to place the components at the most efficient way by it self...
i want to draw the circuit and let the software do all the placing work and routing.

I use traxmaker also, but find I have to do the routing myself! So if someone out there who knows of one that does a good job of auto-routing tube curcuits, I would like to know also. I like doing my own PCB's, but I use mostly point to point!

Originally posted by dud_wity can any one have a suggestion on what software to use?

Don't know about the software, but the hardware to use is the stuff between your ears. Seriously, no autorouter can do nearly as good a job as a thoughtful human. As the designer of the circuit, you will consider where the currents flow, heat, proximity of sensitive components, etc, etc. The autorouter is ignorant of these issues and will produce a very poor layout.

Yeah, most have of us have the "hardware" between our ears, it's the "software" that's missing or defective (corrupted)!
All joking aside, most if not all PCB layout software is geared for double sided digital circuitry. But even then human intervention is always neccesary. If you want good layout with audio circuitry, valve circuitry in particular, you're going to have to do the routing yourself. I usualy draw it out on paper first , then use a prog to make it neat and print it out etc.

I use Protel DXP and my own PCB symbols for octals and novals (and also some nixie-tubes). Autorouting works fine with the symbols, but the best result is always when the human routing software is used (that one between the ears)...

i think that there is a software that do take into considerations heat etc..maybe orcad? up until now i was routing the circuits my self placing the components with the knowledge i poses and at most care for all the problems that can effect the performance of the circuit.
it takes lots of time and not always justify it self.
with non complex circuitry i rather use the best suggestion the software has and apply my corrections.
the best quality an engineer most own is being lazy
i will look for data on the program that was offered
thank you!
best wishes

its a wonderful forum

There is a good tube component library available for Eagle, and Eagle also does have a decent autorouter. In most cases using your intellect works better, however. You can specify design rules (for spacing between HV traces, etc.) for the autorouter to follow. Eagle will also warn you if you violate these design rules in a layout you make yourself.

Using an autorouter for tube circuits is not only unnecessary but also detrimental for the sound. Unless you preroute half the connections the autorouter is guaranteed to produce a circuit with grounding, humming and other non-musical attributes.
